APPLICABILITY OF TSN 400-210 PUMP
The pump belongs to the general-purpose pump group and is designed for pumping water and liquids with properties similar to water in terms of viscosity and chemical activity, with temperatures up to 100 °C, solid content by mass not exceeding 0.05%, maximum particle size of 0.2 mm, and microhardness not exceeding 6.5 MPa (650 kgf/mm²) in water supply systems of industrial and municipal facilities, as well as in agriculture and land reclamation for irrigation and drainage, among other applications.
TECHNICAL SPECIFICATIONS
Nominal parameters of the TSN 400-210 pump and its versions depending on the outer diameter of the impeller.
This parameter must be considered when designing the external network (pipeline and fittings system) and selecting pump equipment.
DIMENSIONS AND WEIGHT
Dimensions and weight of the TSN 400-210 pump and its versions depending on the outer diameter of the impeller.
DRIVE
Asynchronous three-phase induction motors with squirrel-cage rotors are used to drive the TSN 400-210 pump and its versions.
The overall system efficiency (η) ranges from 75% to 72%.
MAIN REQUIREMENTS FOR TSN 400-210 PUMP DESIGN:
- High reliability and cost-effectiveness;
- Extended operating range due to impeller trimming;
- Long service life – average time to major overhaul not less than 28,000 hours (with proper maintenance);
- Dynamic stability across the full range of operating modes;
- Stable, continuously decreasing head curve to ensure reliable operation in parallel operation;
- Correct selection of materials for main parts to ensure required service life;
- High degree of standardization;
- Ease of assembly, disassembly, maintenance, and high repairability under operational conditions.
DESIGN FEATURES OF TSN 400-210 PUMP:
- Horizontal design: ensures high vibration resistance, reduces shaft misalignment risk, and extends component service life;
- Spiral type with horizontal split along the pump axis: allows high maintainability, easy service and installation. Inlet and discharge nozzles located at the bottom and horizontal split allow assembly/disassembly without disconnecting pipelines;
- Four-stage with single-entry impellers;
- Pump casing: complex cast iron structure in two parts (upper – pump cover, lower – pump body) with semi-spiral inlet channels, spiral outlet, and inter-stage transfer channels. Bottom includes inlet/discharge nozzles, support feet, leak collection trays, and bearing mounts. Nozzles are opposite each other, perpendicular to the pump axis. Stage cavities separated by diaphragms and sealing ring;
- Rotor: separate assembly including shaft, impellers, protective bushings, rings, bearings, fasteners, and half-coupling. Impellers secured against axial movement with split rings;
- Symmetric impeller arrangement (discs facing each other) unloads rotor from axial forces;
- Bearings: external rolling bearings. Drive-side bearing (single-row radial ball) handles radial loads; other side (double-row angular contact ball) handles radial and residual axial loads. Lubrication: grease; cooling: air;
- Mechanical gland-type seals with hydraulic seal supply;
- Torque transmission from motor to pump via flexible pin-bushing coupling.
